Researchers have built a chip with the equivalent of 200,000 neurons and 50 million synapses in an effort to mimic a human brain in silicon. I, for one, welcome our simple-minded overlords. From Technology Review:
Although the chip has a fraction of the number of neurons or connections found in a brain, its design allows it to be scaled up, says Karlheinz Meier, a physicist at Heidelberg University, in Germany, who has coordinated the Fast Analog Computing with Emergent Transient States project, or FACETS.
The hope is that recreating the structure of the brain in computer form may help to further our understanding of how to develop massively parallel, powerful new computers, says Meier...
FACETS has been tapping into the same databases. "But rather than simulating neurons," says Karlheinz, "we are building them." Using a standard eight-inch silicon wafer, the researchers recreate the neurons and synapses as circuits of transistors and capacitors, designed to produce the same sort of electrical activity as their biological counterparts.

Eurogamer’s Will Judd flirts with heresy: “Are mechanical keyboards really good for gaming?” When it comes to PC gaming peripherals, stats and specs drive purchases. Gaming monitors became popular because they offered lower latency or higher refresh rates, while gaming mice boasted higher sensitivities and improved tracking accuracy. Yet this quantitative trend doesn’t seem to […]
Tim Cook waved goodbye as Jony Ive pulled out of the car lot for the last time. Without dropping the smile, Cook tilted his head at Jeff Williams. “Finally,” he whispered though his teeth. “We can fix the fucking keyboards” Here’s Benjamin Mayo, quoting Ming-Chi Kuo: Apple to include new scissor switch keyboard in 2019 […]
The escalating tariff slap-fight between the United States of America and the People’s Republic of China is messing with so many bottom lines that the only people playing the market and making bank are those with companies that make red ink in their portfolios. Even Apple, a company that pretty much prints its own damn […]

With enough practice and commitment, anyone can be a visual artist. But without the right instruction, that time spent honing your skills could seem like an eternity. If you really want to see where your talent can take you, you need sound fundamentals – and no matter what discipline or genre you lean toward, the […]
Theoretically, there’s never been an easier time for marketers. The ubiquity of social media means a good word – or a good brand – can spread like wildfire with very little effort. But as limitless as the internet is, there’s a lot of competition and noise to contend with. And the vast graveyard of failed […]
